Answer to Problem 64A

The systematic name of given compound is 2- chlorobutane.

Explanation of Solution

The given compound is

  $\begin{array}{l}{\text{CH}}_{\text{3}}{\text{- CH- CH}}_{\text{2}}\text{-}{\text{CH}}_{\text{3}}\hfill \\ │\hfill \\ \text{ Cl}\hfill \end{array}$

1. Select the longest continuous chain containing the carbon attached the halogen group and this is the parent chain.
2. Number of the carbon atoms of the parent chain, begging from the end nearer to the first substituent whether it is alkyl group or halogen group.

The name of the compound is 2-chlorobutane.

(b)

Interpretation Introduction

Interpretation:

The systematic name of the given haloalkane is to be written.

Concept Introduction:

The given compound is the branched chain alkanes. Various rules are follows to write their IUPAC names

Answer to Problem 64A

The IUPAC name of the given alkane is $\text{1,2-}\text{dibromoethane}$ .

Explanation of Solution

1. Select the longest continuous chain containing the carbon attached the halogen group and this is the parent chain.
2. Number of the carbon atoms of the parent chain, begging from the end nearer to the first substituent whether it is alkyl group or halogen group.
3. Here two haloalkanes group are attached to the parent chain so we use “di” as prefix.

(c)

Answer to Problem 64A

The systematic name of ${\text{CHI}}_{\text{3}}$ is triiodomethane.

Explanation of Solution

1. Select the longest continuous chain containing the carbon attached the halogen group and this is the parent chain.
2. Number of the carbon atoms of the parent chain, begging from the end nearer to the first substituent whether it is alkyl group or halogen group.
3. Here three haloalkanes group are attached to the parent chain so we use “tri” as prefix.

Concept Introduction:

The given compound is the branched chain alkanes. Various rules are follows to write their IUPAC names.

Answer to Problem 64A

The systematic name of given compound is $\text{2,2-}\text{dichloro-4-propylheptane}$ .

Explanation of Solution

1. Select the longest continuous chain containing the carbon attached the halogen group and this is the parent chain.
2. Number of the carbon atoms of the parent chain, begging from the end nearer to the first substituent whether it is alkyl group or halogen group.
3. Here three haloalkanes group are attached to the parent chain so we use “tri” as prefix.
4. If more than one substituent’s are present on the parent chain, these are named in the alphabetical order along with their appropriate positions.

So, the name of the compound is $\text{2,2-}\text{dichloro-4-propylheptane}$
